Product details

Overview

MCP87050T-U/MF from Microchip Technology is an N-channel power MOSFET designed for high-efficiency synchronous buck converters in server and networking point-of-load (POL) applications. It features 4.2 mΩ R_DS(ON) at V_GS = 10 V, 12.5 nC total gate charge, and 1.1 Ω series gate resistance in an 8-lead PDFN 5 mm × 6 mm package.

For engineers reviewing the MCP87050T-U/MF datasheet, MCP87050T-U/MF pinout, MCP87050T-U/MF application, or MCP87050T-U/MF equivalent, key selection criteria include low conduction loss at 20 A, fast switching with 5 ns turn-on delay, short dead-time capability, and thermal performance validated to 150°C junction temperature.

Technical Context

The MCP87050T-U/MF uses advanced silicon processing to achieve a low figure of merit (R_DS(ON) × Q_G) optimized for 12 V input POL converters. Its low Q_GD (4.7 nC) and fast tr/tf (18 ns/5 ns) support high-frequency operation up to 1 MHz while minimizing switching losses.

Designed for synchronous rectification, it integrates an intrinsic body diode with 0.8 V forward voltage and 16 ns reverse recovery time. The exposed drain thermal pad enables low R_θJC (1.9 °C/W), supporting continuous 100 A drain current at T_C = 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	+25 V - Supports 12 V nominal input rails with margin for transient spikes
R_DS(ON)	4.2 mΩ max @ V_GS = 10 V, I_D = 20 A - Enables <1 W conduction loss at 20 A
Q_G	12.5 nC typ - Reduces gate drive power and enables efficient 1 MHz PWM control
Q_GD	4.7 nC typ - Minimizes Miller-induced switching delay and shoot-through risk
t_d(on)/t_f	5 ns / 5 ns - Allows tight dead-time control in synchronous buck topologies
R_θJC	1.9 °C/W - Permits high-power dissipation with direct heatsinking via exposed drain pad
T_J Range	–55°C to +150°C - Qualified for extended-temperature industrial and automotive under-hood use

Pinout & Package

The MCP87050T-U/MF is housed in an 8-lead Plastic Dual Flat, No-Lead (PDFN) package measuring 5 mm × 6 mm × 1.0 mm, with an exposed thermal pad connected to the drain terminals for enhanced thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Low-inductance source connection for high-side or low-side switch placement; tied to PCB ground plane
4	Gate	Control input requiring <13 nC charge; low R_G (1.1 Ω) minimizes ringing and EMI
5, 6, 7, 8 + Exposed Pad	Drain	High-current power path and primary thermal interface; pad must be soldered to large copper area for R_θJC = 1.9 °C/W

Key Features

Feature	Design Value
Low R_DS(ON) × Q_G Figure of Merit	Enables >95% efficiency in 12 V → 1 V POL converters at 20 A, reducing both conduction and switching losses
Fast Turn-On/Turn-Off Timing	5 ns t_d(on) and 5 ns t_f allow dead times below 20 ns, critical for high-frequency synchronous buck stability
Low Q_GD/Q_G Ratio	38% ratio (4.7/12.5 nC) suppresses Miller plateau effects and improves gate drive robustness
Enhanced Body Diode Performance	16 ns t_rr and 20 nC Q_RR reduce reverse-recovery losses during synchronous rectification transitions
RoHS-Compliant PDFN Package	Lead-free 5×6 mm footprint with JEDEC-standard thermal pad layout simplifies PCB thermal design and reflow compatibility

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC014N04LS6	4.2 mΩ R_DS(ON) @ 10 V but higher Q_G (22 nC); same 5×6 mm PQFN package	Higher gate drive loss limits practical frequency to ≤600 kHz vs. MCP87050T-U/MF's 1 MHz capability	Select when board layout prioritizes package compatibility over switching efficiency at >800 kHz
Vishay SiR626DP	4.8 mΩ R_DS(ON) @ 10 V, lower Q_GD (3.8 nC), but only rated to 125°C T_J	Limited high-temperature operation reduces usable current in thermally constrained enclosures	Select for cost-sensitive industrial designs where 125°C max junction suffices and Q_GD is critical

Compared with BSC014N04LS6 and SiR626DP, the MCP87050T-U/MF delivers superior high-frequency efficiency due to its 12.5 nC Q_G and 150°C T_J rating, making it optimal for space-constrained, thermally aggressive POL applications demanding >94% efficiency at 1 MHz.

FAQ

What is the maximum continuous drain current rating for the MCP87050T-U/MF?

The MCP87050T-U/MF is rated for 100 A continuous drain current at T_C = +25°C, as specified in its Absolute Maximum Ratings table. This rating assumes proper PCB thermal design with the exposed drain pad soldered to a minimum 1" × 1" 2 oz. copper area. Derating is required above 25°C case temperature per the SOA curve on page 5 of DS22308B.

Does the MCP87050T-U/MF support gate drive voltages below 4.5 V?

Yes, the MCP87050T-U/MF has a gate threshold voltage (V_GS(TH)) of 1.0–1.6 V, enabling partial enhancement at low gate voltages. However, its R_DS(ON) specification is guaranteed only at V_GS = 4.5 V (6.0 mΩ max) and V_GS = 10 V (5.0 mΩ max); operation below 4.5 V increases conduction loss significantly and is not recommended for high-current applications.

How does the thermal resistance R_θJC of the MCP87050T-U/MF compare to R_θJX?

The MCP87050T-U/MF has R_θJC = 1.9 °C/W (junction-to-case, measured per JEDEC 51-14) and R_θJX = 56 °C/W (junction-to-board, measured on a 4-layer FR4 PCB). R_θJC reflects direct thermal transfer to a heatsink or cold plate, while R_θJX models conduction through the PCB - the 29× difference highlights the critical importance of using the exposed drain pad for effective thermal management.

Is the MCP87050T-U/MF qualified for automotive applications?

The MCP87050T-U/MF is not AEC-Q101 qualified, though its –55°C to +150°C operating junction temperature range and 25 V BVDSS rating meet many automotive subsystem requirements. For production automotive use, Microchip recommends AEC-Q101-qualified alternatives such as the AEC-Q101-compliant variants in the same family; always verify qualification status via Microchip's official automotive product documentation before deployment.

What is the avalanche energy rating of the MCP87050T-U/MF and how is it tested?

The MCP87050T-U/MF has an unclamped inductive switching (UIS) avalanche energy rating of 50 mJ (typical) and 162 mJ (tested condition), measured per JEDEC standard with I_D = 18 A, L = 1 mH, and R_G = 25 Ω. This rating validates robustness against transient overvoltage events during switching, such as those caused by parasitic inductance in high-current PCB traces or load dumps.
